Title: Pilot signal production system
Inventor: KANEZASHI YOSHIO
IPC: H03L7/08
Filed: 1979-12-27
Abstract: PURPOSE:To prevent the pilot signal from disturbing other signals, by changing the oscillation frequency of VCXO toward a low frequency in case the PLL has an out- of-synchronism. CONSTITUTION:A phase comparison is given through the phase comparator 11 between the output signal of the pulse generator 3 and the division output of the divider 9. The output of the comparison produces the negative control voltage Vc through the pulse amplifier 5 and the loop filter 6. The adverse bias voltage of the variable capacity diode 12 increases by the voltage Vc, and thus the oscillation frequency of VCXO including the diode 12 and quartz oscillator 13 to perform a pull-in of synchronism. The voltage Vc becomes minimum with the out-of-synchronism, and accordingly the oscillation frequency of VCXO always changes toward a low level.

Title: Hoisting device
Inventor: YOSHIDA NARITAKA
IPC: B66C1/34
Filed: 1991-07-12
Abstract: PURPOSE:To obtain a small-sized hoisting device which prevents the application of a shock load on a loaded body even in the forcible suspension-up/down by a motor, by installing a shock absorbing means consisting of an energizing means which is positioned between the inner wall of a cylinder and a piston and performs energization in the direction of the separation of both. CONSTITUTION:When suspension-up/down is forcibly carried out by selecting the revolution direction of a motor, i.e., when a chain or wire 6 sharply rises in suspension-up, the shock-applied load due to the sharp rise of the chain or the wire 6 can be absorbed by the buffering action due to a piston 12b and a spring 13 which are installed in the fluid passage of a shock absorbing means 8. When the chain or wire 6 sharply lowers in case of suspension-down, similar operation is carried out, and the bad influence for a product as loaded body 9 can be prevented. Further, since the structure of the shock absorbing means 8 is simple, a small-sized and lightweight simple suspension device can be obtained at a low cost.
